Hi, I have a slight issue with my right thumb joint, it s quite stiff, especially when I m not using it much. I m naturally left-handed, I haven t injured it in anyway to my knowledge. My job is gardening, so I rely on my hands daily. It feels like a nagging pain, that won t go away, should I be concerned? If it s any help I m 28 with no family history of arthritic conditions as far as I know. Thank you.
